夯管法理论问题的探讨

Theoretical Discussion on Pipe-ramming Method

摘要:

分析了夯管锤夯入钢管的过程 ,提出了依据地层压力和动力触探结果计算夯入钢管阻力的方法 ;还提出了应用波动力学计算夯入钢管位移、极限钢管夯入长度及钢管内最大压应力的方法。

Abstract:

Based on the analysis of pipe ramming procedure, this paper presented the method calculating the ramming resistance force according to the results of strata pressure and dynamic probing, and the method calculating displacement, limit length of rammed pipe and max. pressure inside pipe according to wave dynamics.
